Switching visible objects via driver
Below are three spheres with drivers indicated in the properties panel. Please notice the selected object named RenderMaster.  It is used in the drivers.





Below is a simple driver.  Please use copy driver, paste driver then modify for each object to which it is applied.  Not the most compact or elegant, and it will suffice for only 10 objects.  Please notice which sphere is selected so that the driver makes sense as you note the driver adjustments.  Please notice the numbers getting bigger in the Scripted Expression.  Modify and Improve to suit your tastes.









10 different Scripting Expressions.  These are intended for driver expressions in the image above one for each object.


Please test and verify
